Do I need to normalize input parameters to Particle Swarm Optimization?

Hi there,
If the optimizing parameters are in different magnitudes of orders, do I need to scale the upper and lower bounds of the parameters to a scale lilke [1,0]? or does PSO actually do it internally?
Many thanks

You don't usually need to scale your parameters, but many problems are solved more reliably if you do. See Center and Scale Your Problem. I would first try to solve the problem without centering and scaling, and then center and scale if the solver doesn't converge well.
